To create AlgalPure DHA®, we go directly to the source – producing a plant-based vegan omega-3 DHA oil derived from microalgae (the same source that fish get it from). Grown in a controlled environment and made using patented processes – without the use of solvents – AlgalPure DHA® is a rich natural source of the omega-3 fatty acid DHA. Exclusive to Bioriginal, AlgalPure DHA® is a sustainable, plant-based fish oil alternative with outstanding purity, freshness, stability and versatility.
